Mending a Broken Exhaust Manifold

[Forkdriver]

Like a pratt l managed to break the exhaust manifold by catching the vertical exhaust pipe on an overhanging branch. It's one of three outlets on an oldish John Deere 1140, and I have looked online and can't find a replacement. I haven't been able to speak to the dealership yet so has anyone advice on how to get this fixed if I can't get a direct replacement?
Welding or JB weld seem to be the options. Due to its age there's a fair amount of corrosion, but the exhaust box appears good, but bent.

Put up a pic.

Unfortunately it's the horizontal muffler under the bonnet, with an upright pipe from it. I've used Nick Young before and he was very helpful.

There are web sites for used car parts, isn't there one for farm machinery parts?

Basically, a "want" is circulated to all member car breakers who submit offers of what they have and how much. It seems a natural for farm machinery. Sorry, can't be bothered to do a search but Google might come up with something.

Dad hit the bonnet and pushed it back on IH 434 and broke the upright off.

Welded it on with cast rods and an arc welder.

It's held but doesn't look very pretty but is cover by the bonnet

I broke the upright part of a cast manifold on one of my kubotas about 10 years ago and migged it to repair.it don’t look pretty but still ok

Thanks both for the confirmation that welding works. I tried to upload a photo, but it had a link to personal details, so deleted it.

Wow!
I am not worthy. However did you find that? Strangely enough we used to live just a couple of miles from Mark Weston.
Much appreciated. This must be better than a gash weld, so next job is get it ordered. Thanks again.

Aargh, no longer available.

Oh Deere...
The JD parts catalogue doesn't say it's no longer available and it looks like it's a dealer only part if it is anyway. At least you have the pt no...R70410.

Used a bit of trampoline tube on my bobcat exhaust

This is a cast iron manifold with a bend and flare.

We welded steel water pipe to the manifold then the trampoline pipe to that
